Volunteers who develop a cold following virus challenge were significantly slower on choice reaction time tasks than those with no illness. This effect was still observed after the clinical symptoms had gone. In contrast to this, influenza illnesses only impaired performance in tasks in which subjects were uncertain where the target stimulus would appear. These results demonstrate that the CNS effects of respiratory virus infections depend on the type of virus, and that performance impairments may remain even after the symptoms of a cold have gone.
在病毒攻击后患上感冒的志愿者在选择反应时间任务上的表现明显比没有患病的志愿者要慢。即使临床症状消失后，这种影响仍然存在。与此形成对比的是，流感疾病只会在受试者不确定目标刺激会出现在哪里的任务中损害表现。这些结果表明，呼吸道病毒感染对中枢神经系统的影响取决于病毒类型，而且即使感冒症状消失后，表现受损情况可能仍然存在。
